TECHNICAL FIELD

The present invention relates generally to the field of modular storage assemblies. In particular, the present invention relates to a cantilever bracket assembly that can be quickly assembled and disassembled.

BACKGROUND

A clean and well-organized workspace can facilitate a productive work environment and lead to increased efficiency. Storage units that can be adapted to accommodate various types of work allow versatility to a single workspace by maximizing the workspace and creating flexible work environments. Modular storage units are often used in cubicle settings to provide a team environment in which numerous people can be generally located in one area while also providing individual workspaces for each person. By using modular storage units, each workspace can also be adapted to meet the individual needs of each person. For example, various different desks, shelving units, and towers can be connected to the frame of the cubicle to create a personalized workspace.

Because the business world is dynamic, workspaces are constantly changing. Assembling and disassembling the workspaces can be time-consuming and reduce productivity as the work environment is built or modified, resulting in wasted time and money. In addition, some frameworks and storage units may require special tools or expertise to assemble or disassemble. There is therefore a need in the art for an assembly which allows quick installation or modification of existing structures.

DETAILED DESCRIPTION

FIG. 1 shows a schematic view of a bracket assembly 10 for mounting a modular storage unit 12 onto a vertical support assembly 14 having a first vertical standard 14 a and a second vertical standard 14 b. The bracket assembly 10 maintains the storage unit 12 to the vertical support assembly 14 in a cantilevered manner and includes first and second mounting brackets 16 a and 16 b (collectively referred to as “mounting brackets 16”), first and second case brackets 18 a and 18 b (collectively referred to as “case brackets 18”) and first and second locking mechanisms 20 a and 20 b (FIG. 4A) (collectively referred to as “locking mechanisms 20”). The first and second mounting brackets 16 a and 16 b, second case bracket 18 b and first and second locking mechanisms 20 a and 20 b are shown in phantom in FIG. 1. The bracket assembly 10 allows the storage unit 12 to be quickly assembled and disassembled onto the vertical support assembly 14 and can be used in any situation where it is desired to have an easily modifiable system. For example, the bracket assembly 10 may be used in an office environment where individual workspaces are created using a framework structure, such as cubicles. By using the bracket assembly 10 to mount the storage unit 12 onto the vertical support assembly 14, the amount of time and energy expended on creating the work space is reduced. Although FIG. 1 depicts the storage unit 12 as an enclosed shelving unit, any modular unit may be used, such as an open shelving unit, a cabinet or a tray.

FIG. 2A shows a front schematic view of the first mounting bracket 16 a and FIG. 2B shows a bottom schematic view of the first mounting bracket 16 a. The mounting brackets 16 allow quick assembly and disassembly of the case brackets 18 (FIG. 1) to and from the vertical support assembly 14 (FIG. 1). The second mounting bracket 16 b is a mirror-image of the first mounting bracket 16 a and can thus be described cumulatively with reference to the first mounting bracket 16 a. The first mounting bracket 16 a includes a mount flange 22 and a casing 24. The mount flange 22 is substantially L-shaped and includes a first edge 26 and a second edge 28. The first edge 26 includes a first L-shaped protrusion 30 a, a second L-shaped protrusion 30 b, a third L-shaped protrusion 30 c and a fourth L-shaped protrusion 30 d (collectively referred to as “L-shaped protrusions 30”) for engaging the vertical support assembly 14. The first L-shaped protrusion 30 a extends upward to form a hook portion 32 a. Each of the second, third and fourth L-shaped protrusions 30 b, 30 c and 30 d extends downward to form a hook portion 32 b, 32 c and 32 d with a mouth 34 b, 34 c and 34 d, respectively, formed between the hook portion 32 b, 32 c and 32 d and the first edge 26 of the mount flange 22. The second edge 28 of the mount flange 22 connects the mount flange 22 to the casing 24.

The casing 24 has a trailing end 36 and a leading end 38 and is formed as a channel 40 including a guide flange 42, a top flange 44 and a bottom flange 46. The trailing end 36 of the casing 24 is connected to the second edge 28 of the mount flange 22. The top flange 44 extends substantially perpendicularly from a top edge 48 of the guide flange 42. The bottom flange 46 extends substantially perpendicularly from a bottom edge 50 of the guide flange 42 and includes a lip 52. The lip 52 extends substantially perpendicularly from the bottom flange 46 towards the top flange 44 such that the lip 52 is substantially parallel to the guide flange 42. The space formed between the guide flange 42, the top flange 44 and the bottom flange 46 defines the channel 40.

As can be seen in FIG. 2B, the bottom flange 46 also includes a cut-out 54 between the trailing and leading ends 36 and 38 of the casing 24. The cut-out 54 is sized to partially accept the locking mechanism 20 (FIG. 4A). In one embodiment, the cut-out 54 is substantially circular in shape.

FIG. 3 shows a schematic view of the first case bracket 18 a of the bracket assembly 10 (FIG. 1). The case brackets 18 allow the storage unit 12 (FIG. 1) to be easily mounted to the mounting brackets 16 for attachment to the vertical support assembly 14 (FIG. 1). The second case bracket 18 b is a mirror-image of the first case bracket 18 a and can thus be described cumulatively with reference to the first case bracket 18 a. The first case bracket 18 a is formed as a channel 56 having a guide flange 58, a top flange 60 and a bottom flange 62. The top flange 60 is generally L-shaped and extends substantially perpendicularly from a top edge 64 of the guide flange 58. The top flange 60 includes a lip 66 extending substantially perpendicularly from the top flange 60 and away from the bottom flange 62.

The bottom flange 62 extends substantially perpendicularly from a bottom edge 68 of the guide flange 58 and has a first end 70 and a second end 72. The bottom flange 62 includes a lip 74 extending substantially perpendicularly from the bottom flange 62 and away from the top flange 60. The first and second ends 70 and 72 of the bottom flange 62 are sloped away from the guide flange 58 to facilitate insertion of the first mounting bracket 16 a (FIG. 2B) within the first case bracket 18 a. The bottom flange 62 also includes a cut-out 76 between the first and second ends 70, 72 of the bottom flange 62 proximate the lip 74. The cut-out 76 is sized substantially similarly to the cut-out 54 of the first mounting bracket 16 a. In one embodiment, the cut-out 76 is substantially circular in shape.

The space formed between the guide flange 58, the top flange 60 and the bottom flange 62 defines the channel 56. The guide flange 58, the top flange 60 and the bottom flange 62 of the first case bracket 18 a have slightly greater heights than the guiding flange 42, top flange 44 and bottom flange 46, respectively, of the first mounting bracket 16 a. The channel 56 of the first case bracket 18 a is thus slightly taller and wider than the channel 40 of the first case bracket 18 a so that the channel 40 forming the casing 24 of the first mounting bracket 16 a is slidable within the channel 56 of the first case bracket 18 a, as shown in FIG. 5A. The first mounting bracket 16 a is positionable within the first case bracket 18 a such that the cut-out 54 of the first mounting bracket 16 a can be aligned with the cut-out 76 of the first case bracket 18 a.

FIG. 4A shows a schematic view of a ball latch 78 of the bracket assembly 10 (FIG. 1), which functions as a locking mechanism 20 a, 20 b. The ball latch 78 is movable between a relaxed state and a compressed state and includes a sleeve 80 and a ball 82 positionable within the sleeve 80. The sleeve 80 has a first end 84 and a second end 86 with a flange 88 extending from the second end 86. The ball 82 has a rounded end 90 and is extendable from the second end 86 of the sleeve 80 when the ball latch 78 is in the relaxed state. When the ball latch 78 is in the relaxed state, there is no external force or pressure applied to the ball 82 and a spring (not shown) positioned within the sleeve 80 is in an expanded state, maintaining the ball 82 at least partially out of the sleeve 80. When the ball latch 78 is in the compressed state, an external force is applied at the rounded end 90 of the ball 82 such that the spring within the sleeve 80 is compressed to allow the ball 82 to be substantially fully positioned within the sleeve 80.

FIG. 4B shows a schematic view of the ball latch 78 positioned within the first mounting bracket 16 a. To act as a locking mechanism, the ball latch 78 is positioned within the channel 40 of the casing 24 such that the ball 82 of the ball latch 78 extends through the cut-out 54 (FIG. 2B) in the bottom flange 46 of the casing 24. The flange 88 at the second end 86 of the sleeve 80 prevents the ball latch 78 from passing entirely through the cut-out 54 of the first mounting bracket 16 a. The ball latch 78 functions to either allow the first case bracket 18 a (FIG. 3) to be slidable over the first mounting bracket 16 a or to be secured to the first mounting bracket 16 a.

FIGS. 5A and 5B show a front schematic view and a rear schematic view, respectively, of the first mounting bracket 16 a positioned within the first case bracket 18 a. Because the first and second ends 70, 72 of the bottom flange 62 are sloped away from the bottom edge 68 of the guide flange 58, the ball 82 of the ball latch 78 (FIG. 4A) is slowly compressed as the first case bracket 18 a slides around the first mounting bracket 16 a. With the ball 82 compressed within the sleeve 80, the first case bracket 18 a can slide over the first mounting bracket 16 a without any interference from the ball latch 78. When the cut-out 76 of the first case bracket 18 a aligns with the cut-out 54 (FIG. 2B) of the first mounting bracket 16 a and the ball latch 78, the ball 82 is no longer compressed by the first case bracket 18 a and deploys through the cut-out 76 of the first case bracket 18 a. In this position, the ball 82 prevents the first case bracket 18 a from moving relative to the first mounting bracket 16 a.

To disconnect the first case bracket 18 a from the first mounting bracket 16 a, the ball 82 of the ball latch 78 is compressed into the sleeve 80 of the ball latch 78 so that the first case bracket 18 a can move relative to the first mounting bracket 16 a. When the ball 82 of the ball latch 78 no longer extends through the cut-out 76 of the first case bracket 18 a, the first case bracket 18 a is free to slide over the first mounting bracket 16 a and to be removed from around the first mounting bracket 16 a. The ball latch 78 thus allows the first case bracket 18 a to be in either a first, unlocked position or a second, locked position relative to the first mounting bracket 16 a.

Referring to all of the previous figures, a method of mounting the storage unit 12 onto the vertical support assembly 14 using the bracket assembly 10 is described. To mount the storage unit 12 onto the vertical support assembly 14, the first mounting bracket 16 a is first mounted onto the first vertical standard 14 a. The first vertical standard 14 a includes a plurality of apertures (not shown) running the length of the vertical standard 14 a. The apertures are sized to accept the L-shaped protrusions 30 of the first mounting bracket 16 a. The hook portions 32 b, 32 c and 32 d of the second, third and fourth protrusions 30 b, 30 c and 30 d, respectively, function to lock the first mounting bracket 16 a to the vertical support assembly 14 a. To prevent the first mounting bracket 16 a from being inadvertently displaced in the upward direction, the hook portion 32 a of the first L-shaped protrusion 30 a extends upward to provide an anti-disengagement feature.

Each of the apertures of the first vertical standard 14 a is defined by a top edge of material and a bottom edge of material. The method of assembling includes inserting the hook portions 32 of the L-shaped protrusions 30 into the apertures. Following insertion of the hook portions 32 of the L-shaped protrusions 30 into the apertures, the first mounting bracket 16 a is moved downward. As the first mounting bracket 16 a is moved downward, the hook portions 32 b, 32 c and 32 d of the second, third and fourth protrusions 30 b, 30 c and 30 d, respectively, rest against the bottom edges of material of the first vertical standard 14 a such that the bottom edges of material are received in the mouths 34 b, 34 c and 34 d of the hook portions 32 b, 32 c and 32 d, respectively. The mouths 34 b, 34 c and 34 d of the hook portions 32 b, 32 c and 32 d, respectively, act to releasably retain the first mounting bracket 16 a to the first vertical standard 14 a. The hook portion 32 a of the first L-shaped protrusion 30 a prevents the first mounting bracket 16 a from lifting and disengaging from the aperture of the first vertical standard 14 a.

The second mounting bracket 16 b (FIG. 1) is similarly inserted into apertures in the second vertical standard 14 b (FIG. 1) and moved downward to releasably retain the second mounting bracket 16 b to an attachment site defined by the second vertical standard 14 b.

In one embodiment, after the mounting brackets 16 are mounted onto the vertical standards 14, the first and second vertical standards 14 a and 14 b are spaced apart from one another at a distance substantially equal to a width of the storage unit 12. Before mounting the storage unit 12 onto the mounting brackets 16, the case brackets 18 are attached to the storage unit 12. In one embodiment, the case brackets 18 are attached to opposing interior walls of the storage unit 12 at the lips 66 of the top flanges 60 and the lips 74 of the bottom flanges 62 of the case brackets 18. The case brackets 18 can be attached to the storage unit 12 by any suitable means known in the art. In one embodiment, the case brackets 18 are welded to the storage unit 12.

Once the case brackets 18 are attached to the storage unit 12, the storage unit 12 with the case brackets 18 is moved towards the mounting brackets 16 such that the channels 56 of the case brackets 18 are aligned with the channels 40 of the mounting brackets 16. The case brackets 18 are then slid over the casings 24 of the mounting brackets 16. Because the first and second ends 70, 72 of the bottom flanges 62 of the case brackets 18 are sloped, the ball latches 78 are compressed with the balls 82 positioned within the sleeves 80 as the case brackets 18 are pushed over the mounting brackets 16, allowing the case brackets 18 to slide over the mounting brackets 16.

As mentioned above, when the cut-outs 76 of the case brackets 18 reach the ball latches 78, the balls 82 deploy from the sleeves 80 and extend through the cut-outs 76 of the case brackets 18. When the balls 82 extend through the cut-outs 76 of the case brackets 18, the case brackets 18, and thus the storage unit 12, are locked to the mounting brackets 16.

By assembling the bracket assembly 10 as described above, the mounting brackets 16 provide a means for releasably securing the storage unit 12 to the vertical support assembly 14. From the preceding description, it should be understood that the weight of the storage unit 12 optionally assists with retaining the mounting brackets 16 in the downward, secure position.

When it is desired to remove the storage unit 12 from the vertical support assembly 14 and the mounting brackets 16, the balls 82 of the ball latches 78 are compressed back into the sleeves 80 until they no longer engage the cut-outs 76 of the case brackets 18. Because the ball latches 78 no longer engage the cut-outs 76, the case brackets 18 are free to slide relative to the mounting brackets 16 as described above. The case brackets 18 and the storage unit 12 can then be removed from the mounting brackets 16.

To remove the mounting brackets 16 from the vertical support assembly 14, the mounting brackets 16 are slid upward and moved outward and away from the vertical support assembly 14. The hook portions 32 of the L-shaped protrusions 30 are then removed from the apertures, removing the mounting brackets 16 from the vertical support assembly 14.

FIG. 6 shows a schematic view of a first mounting bracket 102 a, which is a second embodiment of the first mounting bracket 16 a. Similar to the first embodiment of the first mounting bracket 16 a shown in FIG. 2A, the second embodiment of the first mounting bracket 102 a includes a mount flange 108 connected substantially perpendicularly to a casing 110. The second embodiment of the mount flange 108 has substantially similar features and functions substantially similarly to the first embodiment of the mount flange 22.

The second embodiment of the casing 110 of the first mounting bracket 102 a is also substantially similar to the first embodiment of the casing 24 of the first mounting bracket 16 a except that the casing 110 includes a top cut-out 112 at a top flange 114 of the casing 110 and a bottom cut-out 116 at a bottom flange 118 of the casing 110, and the bottom flange 118 of the casing 110 does not include a lip. The cut-outs 112 and 116 at the top and bottom flanges 114 and 118, respectively, are aligned with one another. In one embodiment, the cut-outs 112 and 116 are substantially rectangular with the top cut-out 112 being slightly larger than the bottom cut-out 116. Other than the top and bottom cut-outs 112 and 116 of the casing 110, the second embodiment of the casing 110 includes the same features and functions substantially similarly to the first embodiment of the casing 24.

FIG. 7 shows a schematic view of a first case bracket 104 a, which is a second embodiment of the first case bracket 18 a. The second embodiment of the first case bracket 104 a is substantially similar to the first embodiment of the first case bracket 18 a except that the first case bracket 104 a includes a top cut-out 120 (shown in phantom) at a top flange 122 of the first case bracket 104 a and a bottom cut-out 124 at a bottom flange 126 of the first case bracket 104 a. Similar to the cut-outs 112 and 116 of the first mounting bracket 16 a, the cut-outs 120 and 124 are aligned with one another. In addition, the bottom flange 126 of the first case bracket 104 a is substantially linear and is not sloped at its ends. In one embodiment, the cut-outs 120 and 124 are substantially rectangular and are sized substantially similarly to the cut-outs 112 and 116 of the first mounting bracket 102 a, respectively. Otherwise, the second embodiment of the first case bracket 104 a includes the same features and functions substantially similarly to the first embodiment of the first case bracket 18 a.

The second embodiments of the first mounting bracket 102 a and the first case bracket 104 a interact with each other in a substantially similar manner as the first embodiments of the first mounting bracket 16 a and the first mounting bracket 18 a. To mount the storage unit 12 onto the vertical support assembly 14 (FIG. 1) using the second embodiments of the first mounting bracket 102 a and the first case bracket 104 a, the first case bracket 104 a is first slipped over the first mounting bracket 102 a until the top cut-outs 112 and 120 of the first mounting bracket 102 a and the first case bracket 104 a, respectively, are aligned and the bottom cut-outs 116 and 124 of the first mounting bracket 102 a and the first case bracket 104 a, respectively, are aligned. The first case bracket 104 a can then be locked in position relative to the first mounting bracket 102 a using a spring clip 126 (FIG. 8A).

FIG. 8A shows a schematic view of a second embodiment of the locking mechanism 20 a (FIG. 4A), including the spring clip 126. FIG. 8B shows a perspective view of the spring clip 126 positioned within the first mounting bracket 102 a and the first case bracket 104 a. The spring clip 126 maintains the first case bracket 104 a to the first mounting bracket 102 a and functions similarly to the ball latch 78 of the bracket assembly 10 (FIG. 1). The spring clip 126 includes a substantially V-shaped body portion 128 having a first end 130 and a second end 132. The first end 130 includes a first protrusion 134 sized to engage the top cut-outs 112 and 120 of the first mounting bracket 102 a and the first case bracket 104 a, respectively. Similarly, the second end 134 includes a second protrusion 136 sized to engage the bottom cut-outs 116 and 124 of the first mounting bracket 102 a and the first case bracket 104 a, respectively.

Referring also to FIGS. 6 and 7, the spring clip 126 is movable between a relaxed state and a compressed state. When the spring clip 126 is in the relaxed state (FIG. 8A), the first and second ends 130, 132 are substantially parallel to each other and are spaced from each other at a distance substantially equal to a distance between the top flange 114 and the bottom flange 118 of the first mounting bracket 102 a. When the spring clip 126 is in the compressed state, the first and second ends 130 and 132 are pushed towards each other such that the spring clip 126 can be positioned between the top flange 114 and the bottom flange 118 of the first mounting bracket 102 a.

To position the spring clip 126 within the first mounting bracket 102 a and the first case bracket 104, the spring clip 126 is compressed and positioned between the top flange 114 and the bottom flange 118 of the first mounting bracket 102 a. The first protrusion 134 is aligned with the top cut-outs 112 and 120 of the first mounting bracket 102 a and the first case bracket 104 a, respectively, and the second protrusion 136 is aligned with the bottom cut-outs 116 and 124 of the first mounting bracket 102 a and the first case bracket 104 a, respectively.

The spring clip 126 is then released to its relaxed state such that the first and second protrusions 134 and 136 of the spring clip 126 engage the top cut-outs 112 and 120 and bottom cut-outs 116, 124 of the first mounting bracket 102 a and the first case bracket 104 a, respectively. In this position, the first protrusion 134 the spring clip 126 extends through the top cut-outs 112 and 120 of the first mounting bracket 102 a and the first case bracket 104 a, respectively, and the second protrusion 136 extends through the bottom cut-outs 116 and 124 of the first mounting bracket 102 a and the first case bracket 104 a, respectively, to lock the first case bracket 104 a in position relative to the first mounting bracket 102 a.

To remove the first case bracket 104 a from the first mounting bracket 102 a, the first and second ends 130, 132 of the spring clips 126 are compressed towards each other to disengage the first protrusion 134 of the spring clip 126 from the top cut-outs 112 and 120 and to disengage the second protrusion 136 of the spring clip 126 from the bottom cut-outs 116 and 124. Once the spring clip 126 is disengaged from the first mounting bracket 102 a and the first case bracket 104 a, the spring clip 126 can be removed from within the first mounting bracket 102 a. The first case bracket 104 a is then free to slide off of the first mounting bracket 102 a.

FIG. 9 shows a schematic view of a first mounting bracket 202 a, which is a third embodiment of the first mounting bracket 16 a, connected to the first vertical standard 14 a. Similar to the first embodiment of the first mounting bracket 16 a (FIG. 2A), the third embodiment of the mounting bracket 202 a includes a mount flange 208 and a casing 210. The mount flange 208 includes a first edge 212 (shown in phantom) and a second edge 214 spaced from the first edge 212 such that the mount flange 208 is substantially C-shaped. The first and second edges 212 and 214 of the mount flange 208 are spaced a distance from each other to allow the mount flange 208 to wrap around part of the first vertical standard 14 a. The mount flange 208 is connected to the casing 210 at the second edge 214 of the mount flange 208 at a substantially 90 degree angle.

The casing 210 includes a guide flange 216 having a trailing end 218, a leading end 220, a top flange 222 and a bottom flange 224. The casing 210 is connected to the second edge 214 of the mount flange 208 at the trailing end 218 of the guide flange 216. The top flange 222 extends along a top edge 226 of the guide flange 216 from the trailing end 218 past the leading end 220 of the guide flange 216 and ends in a tip portion 228. The tip portion 228 of the top flange 222 is rounded and slightly bent downward to provide a lead-in into the casing 210. The top flange 222 includes a top cut-out 230 that extends from the tip portion 228 of the top flange 222 towards the trailing end 218 of the guide flange 216. The top cut-out 230 allows a spring clip 232 (FIG. 11) to act unimpeded by the thickness of the top material of the casing 210.

The bottom flange 224 begins between the trailing end 218 and the leading end 220 of the guide flange 216 and extends past the leading end 220 of the guide flange 216 and ends in a rounded tip portion 234. The bottom flange 224 is slightly wider than the top flange 222 and the tip portion 234 of the bottom flange 224 extends slightly farther past the leading end 220 of the guide flange 216 than the tip portion 228 of the top flange 222. The bottom flange 224 includes a bottom cut-out 236 located proximate the leading end 220 of the guide flange 216 and provides connection with the spring clip 232. At least a portion of the bottom cut-out 236 is aligned with the top cut-out 230. In one embodiment, the cut-outs 230 and 236 are substantially rectangular with the top cut-out 230 being longer than the bottom cut-out 236.

The guide flange 216 includes an engagement feature 238 proximate the trailing end 218 that extends from the guide flange 216 between the top and bottom flanges 222 and 224. The engagement feature 238 provides strength and resistance to the bracket assembly 100 to prevent the case bracket 204 (FIG. 10) from rotating forward. In one embodiment, the engagement feature 238 is stamped from the guide flange 216.

FIG. 10 shows a schematic view of a first case bracket 204 a, which is a third embodiment of the first case bracket 18 a. The third embodiment of the first case bracket 204 a is substantially similar to the second embodiment of the first case bracket 104 a (FIG. 7) and has a leading end 240, a trailing end 242, a guide flange 244, a top flange 246 and a bottom flange 248. The primary difference between the second embodiment of the first case bracket 104 a and the third embodiment of the first case bracket 204 a is that the first case bracket 204 a only has one cut-out 250 (shown in phantom) through the top flange 246 of the first case bracket 204 a. The cut-out 250 is located proximate the leading end 240 of the first case bracket 204 a and is alignable with the top cut-out 230 of the casing 210 (FIG. 9). In one embodiment, the cut-out 250 is substantially rectangular.

The third embodiments of the first mounting bracket 202 a and the first case bracket 204 a interact with each other in a substantially similar manner as the first embodiments of the first mounting bracket 16 a and the first mounting bracket 18 a. To mount the storage unit 12 (FIG. 1) using the third embodiments of the first mounting bracket 202 a and the first case bracket 204 a, the first case bracket 204 a is first slipped over the first mounting bracket 202 a until the top cut-outs 230 and 250 of the first mounting bracket 202 a and the first case bracket 204 a are aligned. The first case bracket 204 a can then be locked in position relative to the first mounting bracket 202 a using a spring clip 232 (FIG. 11).

FIG. 11 shows a schematic view of a third embodiment of the locking mechanism 20 a (FIG. 4A), including the spring clip 232. The spring clip 232 maintains the first case bracket 204 a to the first mounting bracket 202 a. The spring clip 232 includes a lever arm 252 and a spring arm 254. The lever arm 252 has a first end 256 and a hook portion 258 at a second end 260. The lever arm 252 is connected to the spring arm 254 at the first end 256, which includes a protrusion 262 sized to engage the bottom cut-out 236 of the first mounting bracket 202 a.

The spring arm 254 of the spring clip 232 includes a first end 264, a second end 266 and a middle portion 268. The second end 266 of the spring arm 254 is attached to the first end 256 of the lever arm 252 at an angle such that the lever arm 252 and the spring arm 254 form a shape substantially similar to a V-shape. The middle portion 268 of the spring arm 254 is curved and allows the first end 264 of the spring arm 254 to be compressed without overbending the spring clip 232. The spring clip 232 includes a rivet hole 270 between the lever arm 252 and the spring arm 254 and allows the spring clip 232 to be rotatably attached to a rivet hole 272 in the guide flange 244 of the first case bracket 204 a by a rivet 274 (FIG. 12A).

FIG. 12B shows an enlarged perspective view of the spring clip 232 positioned within the first mounting bracket 204 a in a compressed state. When the spring clip 232 is in the compressed state, the lever arm 252 and the spring arm 254 are pushed towards each other such that the spring clip 232 can be positioned between the top flange 222 and the bottom flange 224 of the casing 210. Referring also to FIGS. 9, 10 and 11, the spring clip 232 is positioned within the casing 210 such that the hook portion 260 of the lever arm 252 engages the bottom flange 224 of the first mounting bracket 202 a at the leading end 220 of the guide flange 216 and the bottom flange 248 of the first case bracket 204 a at the leading end 240 of the guide flange 244. In this position, the first end 264 of the spring arm 254 extends through the top cut-out 230 of the top flange 222 of the casing 210 and the cut-out 250 of the first case bracket 204 a, allowing adjustment of the first case bracket 204 a relative to the first mounting bracket 202 a.

FIG. 12A shows an enlarged perspective view of the spring clip 232 positioned within the first mounting bracket 204 a in a relaxed state. The rivet hole 270 of the spring arm 254 allows the spring clip 232 to rotate within the first case bracket 204 a between the compressed state and the relaxed state. In the relaxed state, the lever arm 252 and the spring arm 254 are spaced from each another at a distance substantially equal to the distance between the top flange 222 and the bottom flange 224 of the casing 210. In the relaxed position, the protrusion 262 of the lever arm 252 is positioned to interface with the bottom cut-out 236 of the bottom flange 224 of the casing 210 to prevent movement and rotation. The first end 264 of the spring arm 254 also extends through the cut-out 230 of the top flange 222 of the casing 210 and contacts the top flange 246 of the first case bracket 204 a, locking the first case bracket 204 a to the first mounting bracket 202 a.

To release the spring clip 232, the spring clip 232 is moved to the compressed state. The spring clip 232 is disengaged by pressing up on the lever arm 252 of the spring clip 232. The shape of the lever arm 252 and its relationship to the casing 210 and the first case bracket 204 a prevents the spring clip 232 from overbending and breaking. As the lever arm 252 is pushed up, the first end 264 of the spring arm 254 slides along the top flange 246 of the first case bracket 204 a until it extends through the cut-out 250 of the top flange 246 of the first case bracket 204 a. Once the spring arm 254 extends through the cut-out 250, the hook portion 260 can be removed from the bottom flanges 224 and 248 of the first mounting bracket 202 a and the first case bracket 204 a, respectively. After the hook portion 260 of the lever arm 252 is disengaged from bottom flanges 224 and 248, the spring arm 254 is removed from the top cut-outs 230, 250 of the casing 210 and the first case bracket 204 a, respectively. The first case bracket 204 a is then free to slide off the first mounting bracket 202 a.
